I have yet to replace the plugs on my 258, which had the MPI kit on it when I bought it (thus my lack of written directions).
Anyone with the kit (but not the 4.0 heads) have any advice as to a good plug to use. More importantly, what gap are you using?
Any feedback pos. or neg. would be appriciated.
